The effect of raw jackfruit (Artocarpus heterophyllus) seed meal (JFM) on performance, nutrient utilization and economics of production was investigated using 144 broiler chickens.The birds were divided into four dietary treatments of 3 replicates and 12 birds per replicate in a completely randomized design. Diet one was soybean based (control) while raw JFM meal was added to diets 2 (T ), 3 (T ) and 4 (T ) at 10, 20 and 30% levels of inclusion 2 3 4 of soybean meal in the control diet respectively. At 8 weeks, 2 birds per replicate were used to evaluate nutrient utilization. The growth performance was generally depressed with increased inclusion of raw JFM in the diets. The feed to gain ratio of birds placed on control diet (2.55) and T (2.56) were the same (P>0.05) and are significantly better (P < 0.05) than 2 other treatments. Nitrogen, ether extract and ash retention were virtually the same for birds fed T T and T while energy retention was higher (P<0.05) in birds fed T (2,82MJ/Kg ME) 1, 2 3 1 than those fed T , T and T .The cost per Kg feed was higher in T (? 131.59) and decreased 2 3 4 1 with increase in inclusion of raw JFM; T (? 127.17), T (? 123.66) and T (? 123.24). Cost per 2 3 4 Kg weight gain, revenue and gross margin were the same for birds fed control and those fed with T . From the foregoing raw JFM is a potential feed resource and could be included in the 2 diet of broiler chicken up to 10% level of inclusion of soybean meal in a control diet.

Effect of toasted jackfruit (Artocarpus heterophyllus) seed meal (TJSM) on performance of 120 2 weeks old broiler chickens was investigated. The birds were divided into four dietary treatments having 3 replicates and 10 birds per replicate in a completely randomized design. Diet one (T) was soybean based while toasted JFSM meal was added to diets 2 (T), 3 (T) 1 2 3 and 4 (T) at 5, 10 and 15% levels of inclusion, respectively. Growth performance was 4 generally depressed with increased inclusion of toasted JFSM in the diets. Feed conversion ratio of birds fed T and T were the same and significantly better (P>0.05) than those of the 1 2 remaining treatment groups. Birds fed T had significantly higher values of live weight, 1 dressed weight and dressing percentage followed by birds fed T. The prime cut parts were 2 similar in all the treatment groups. Organ proportions showed no significant differences across the treatment groups except the spleen. Cost per kg feed decreased with increased inclusion of TJSM. The cost of feed consumed was higher (P>0.05) in T (531.29) but 1 decreased with increased inclusion of TJSM. The cost per kg weight gain, cost of production and revenue were similar across the treatment groups with birds fed T significantly higher 1 (P>0.05) than the remaining treatment groups. The gross margin obtained for birds fed T 1 and T are comparable and higher than other treatment groups. From the foregoing TJFSM is 2 a potential feed resource and could be included in the diet of broiler chickens up to 5% inclusion level.

This study investigated the use of cooked sunflower seed meal as soybean meal replacer in Clarias gariepinus diet in a 56-day feeding trial using growth performance, nutrient utilization, body composition, digestibility, haematology and liver histology as indices of assessment. Sunflower seed meal was cooked for 10, 20 and 30 minutes. Each of the differently cooked sunflower seed meal replaced soybean meal portion of control diet at 15, 30 and 45% to produce nine 40% crude protein, 18kj/kg test diets. A diet without sunflower meal served as the control. Triplicate groups of fish in 70-litre capacity aerated rectangular plastic tanks were alloted to each dietary treatment at a stocking rate of 15 fingerlings (3.72±0.22g average weight) per tank in a completely randomized design. Fish were fed to satiation. Data obtained from the experiment were subjected to statistical analysis. The results of the experiment revealed that up to 30% replacement level of 10- and 20-minutes cooked sunflower produced a statistically similar results with soybean-based control diets.

Deficit of conventional feed ingredients in meeting increased demand has led to an alarming hike in their prices culminating in sky rocketing cost of livestock feed. This has necessitated an urgent search for low cost and more readily available alternatives. This study was conducted to investigate the performance of broiler chicks fed diets containing graded levels of soaked and boiled Bambara nut seed meal (BNSM). One hundred and five (105), 2 week old broiler starter chicks were used for the experiment. The birds were randomly allotted into four dietary treatments with each treatments replicated thrice at seven birds per replicate in a completely randomized design. Five experimental diets were formulated containing processed BNSM designated as T1 (control diet with 0 % BNSM), while T2, T3, T4 and T5 had 5 % soaked BNSM, 10 % soaked BNSM, 5 % boiled BNSM and 10 % boiled BNSM, respectively. The experiment lasted for four (4) weeks. Feed and water were provided ad libitum. The results showed that birds fed processed BNSM diets had significantly (P<0.05) higher final weight and weight gain comparable to 702.38g and 19.99 g/bird/day in the control group. The values obtained from feed intake showed that T2 (64.74 g) had significantly (P<0.05) least value compared to other dietary treatments. Feed conversion ratio and feed cost per kg gain (N) were significantly (P<0.05) better in birds fed processed BNSM diets compared to 3.39 and N215.85 respectively in the control group. It was therefore concluded that processed BNSM improved performance of broiler chickens.     Le déficit d'ingrédients alimentaires conventionnels pour répondre à la demande accrue a conduit à une hausse alarmante de leurs prix, aboutissant à une flambée du coût des aliments pour le bétail. Cela a nécessité une recherche urgente d'alternatives peu coûteuses et plus facilement disponibles. Cette étude a été menée pour étudier la performance des poussins de départ de pouletsde chair nourris avec des régimes contenant des niveaux échelonnés de farine de graines de noix de Bambara trempées et bouillies. Cent cinq (105) poussins de départ âgés de 2 semaines ont été utilisés pour l'expérience. Les oiseaux ont été répartis au hasard en quatre traitements diététiques, chaque traitement étant répliqué trois fois à raison de sept oiseaux par réplique dans une conception complètement aléatoire. Cinq régimes expérimentaux ont été formulés contenant du 'BNSM'-Bambara nutseedmeal(Aliment de farine de graines de noix de bambara)- traité désigné comme T1 (régime témoin avec 0% de BNSM), tandis que T2, T3, T4 et T5 contenaient 5% de 'BNSM' imbibé, 10% de 'BNSM' imbibé, 5% de 'BNSM' bouilli et 10% de 'BNSM' bouilli, respectivement. L'expérience a duré quatre (4) semaines. L'alimentation et l'eau étaient fournies ad libitum. Les resultants ontmontré que les oiseaux nourris avec des régimes 'BNSM' transformés avaient un poids final et un gain de poids significativement plus élevés (P <0.05) comparables à 702.38 g et 19.99 g / oiseau / jour dans le groupe témoin. Les valeurs obtenues à partir de la consommation alimentaire ont montré que T2 (64.74 g) avait une valeur significativement moindre (P <0.05) par rapport aux autres traitements diététiques. Le taux de conversion alimentaire et le coût alimentaire par kg de gain (N) étaient significativement meilleurs (P <0.05) chez les oiseaux nourris avec des régimes 'BNSM' transformés par rapport à 3.39 et N215.85 respectivement dans le groupe témoin. Il a donc été conclu que le 'BNSM' transformé améliorait les performances despoussins de départ de poulets de chair.

This study was carried out to investigate the effect of equi-protein replacement of soybean meal with groundnut cake on immune status, haematology and serum biochemical parameters of broiler chickens. A total of One hundred and twenty (120) Cobb’s day old chicks were randomly allocated to five (5) dietary treatments of three (3) replicates and eight (8) chicks per replicate in a completely randomized design. The Diet I was the control diet with 100% SBM as the major plant protein source while in other diets, SBM was replaced with 25, 50, 75 and 100% GNC in equi-protein basis and designated as Diets II, III, IV and V respectively. Feed and water were provided ad-libitum throughout the experimental period of 56 days. Newcastle disease (ND) vaccines were administered following a stipulated regime. At the end of the experiment two birds were randomly selected from each replicate and slaughtered. Blood and serum was collected for haematological analysis, serum bioassay and HA/HI tests to determine antibody titres against ND vaccines. All data collected were subjected to one-way analysis of variance using SPSS software package. Results showed that haematological parameters were significantly influenced by the dietary treatments in which birds fed 50% equi-protein replacement of SBM with GNC had better PCV, basophil, MCH and MCHC values compared to that of birds in the other dietary treatments. The antibody titres of experimental birds were not significantly different among treatment groups. The diet with 50% equi-protein replacement of SBM with GNC elicited the highest antibody titres of Log28 and Log210 after the 1st and 2nd ND vaccinations when compared to the other diets. The serum total protein, globulin, albumin, and glucose were significantly influenced by the dietary treatments. The present result indicate that 50% equi-protein replacement of SBM with GNC in diets is not detrimental to health status of broiler chickens.

Growth performance, carcass characteristics and economics of broiler chicken fed graded levels of raw Mucuna sloanei seed meal were investigated. A total of 150, 1- day old broiler chickens were used. There were five treatments each replicated into three with 10 birds per replicate in a completely randomized design. Five treatment diets were formulated. Diet 1served as control, while diets 2, 3, 4, and 5 had 5, 10, 15, and 20 %, respectively of raw mucuna seed meals (RMSM) added to them. The experiment lasted 49 days. The parameters considered were growth performance, carcass characteristics and economics of production. For growth performance, the result revealed that RMSM significantly (P<0.05) depressed growth as the levels of inclusion of RMSM increased from 0 to 20%. There were significant differences (p<0.05) in all the parameters considered under growth except for initial body weight and mortality. There was progressive loss in final body weight as the level of mucuna inclusion increased from 0% to 20%. Control recorded the highest live body weight of 3023.30g while, birds fed diet with 20% mucuna had the least body weight of 504.43g. Among the birds placed on the test diets, birds fed diet with 5% mucuna seed meal performed significantly (P<0.05) better (1840.00g) than other test diets. Birds fed diets with 10 and 15% mucuna had final body weight of 1180.00 and 726.67g, respectively. The progressive l oss in weight was obvious early in the experiment and at 8 weeks of age the broiler fed 20% raw mucuna. Mucuna sloanei based diet weighed only 504.43g (16.68% of the control) as against 1840.00, (60.86% of the control) for that fed 5%.mucuna. Percentage dressed weight and percentage breast and thigh were significantly (P<0.05) higher for chicken fed control diet. 10% level of raw MSSM gave highest value for drumstick (14.91%) while control gave the least (13.00%). 5% raw MSSM (27. 71%) compared favourably with control (30.60%) for breast cut. Gross margin significantly decreased from N1459.80 for control diet to N 14.20 for D5 as the percentage inclusion of MSSM increases from 0 to 20%. In conclusion, birds fed raw Mucuna sloanei seed meal diet could not compare favourably with those fed soya bean based diets even at 5% level of inclusion. Processing is therefore recommended to enhance performance.

Abstract Background: Compared to the corresponding source of inorganic trace minerals (TM), chelated supplements are characterized by better physical heterogeneity and chemical stability and appear to be better absorbed in the gut due to possibly decreased interaction with other feed components. This study was designed in broiler chickens to determine the effects of replacing inorganic trace minerals (TM) with an advanced chelate technology based supplement (Bonzachicken) on growth performance, mineral digestibility, tibia bone quality, and antioxidant status. A total of 625 male 1-d-old broiler chickens were allocated to 25 pens and assigned to 5 dietary treatments in a completely randomized design. Chelated TM (CTM) supplement was compared at 3 levels to no TM (NTM) or inorganic TM. A corn–soy-based control diet was supplemented with inorganic TM at the commercially recommended levels (ITM), i.e., iron, zinc, manganese, copper, selenium, iodine, and chromium at 80, 92, 100, 16, 0.3, 1.2, and 0.1 mg/kg, respectively, and varying concentration of CTM, i.e., match to 25, 50, and 100 % of the ITM (diets CTM25, CTM50, and CTM100, respectively). Results: All diets, except diet CTM25, increased average daily gain (ADG), European performance index (EPI), and serum total antioxidant capacity compared to the NTM diet (P < 0.05). Broilers fed the CTM100 diet had lowest overall FCR and highest BWG, EPI, tibia ash, zinc, and manganese contents (P < 0.05). The tibia phosphorus content and apparent ileal digestibilities of phosphorus, zinc, and manganese were lower in the ITM group compared with the CTM50 and CTM100 groups (P < 0.05). Broiler chickens fed any of the diets exhibited higher serum glutathione peroxidase and superoxide dismutase activities and lower malondialdehyde level than those fed the NTM diet, where the best values were found for CTM100 treatment (P < 0.05). Conclusions: These results indicate that while CTM supplementation to 25 and 50% of the commercially recommended levels could support growth performance, a totally replacing ITM by equivalent levels of CTM could also improve growth performance, bone mineralization and antioxidant status of broiler chickens under the conditions of this study.

Abstract The feed quality have direct/indirect impact on the blood profiles of animal and determines health status. Hence, this study was carried out to investigate the dietary effect of T. nilotica seed meal (TNSM) on haematology and serum biochemical indices of goats. 15 West African Dwarf goats with a similar age range of 12-18 months old and body/live-weight of 6.88±0.26 kg were randomly allocated to 5 dietary treatments with 3 goats per replicate in a Completely Randomized Design arrangement for 12 weeks. Unprocessed TNSM were collected, screened and milled and were used to replace palm kernel cake at 20% (diet B), 30% (diet C), 40% (diet D) and 50% (diet E) replacement levels in a complete concentrate diets while diet A (control diet) had no T. nilotica. Nutrient composition, intake and animals' blood samples were assessed. Results revealed that all parameters observed were significantly (p<0.05) different. At 20%, DWG, FGR were best. PCV, RBC, Hb values of the goats decreased with increased with replacement level of PKC with TNSM. It could be concluded that TNSM could serve as protein source in place of PKC in goat diet up to 20% without any adverse effects on growth and health status.

A study was conducted to investigate the effect of sorghum based diets supplemented with enzyme on haematological and serum biochemical responses of grower rabbits. A total of twenty four grower rabbits were used for the investigation which lasted eight weeks. Four experimental diets were formulated which included maize based diet (Control), sorghum based diet supplemented with; Protease (D2), Phytase (D3) and PhytasewithProtease(D4).The rabbits were randomly assigned to the four dietary treatments in a completely randomized design. Rabbitsfed diet containing sorghum with phytase (D3)had high significant (p< 0.05) value of 115.10g for final weight. Least statistically similar values of 1136.80g and 1033.60g were obtained for rabbit fed sorghum with protease plus phytase (D4) and control diet, respectively. The weight gain followed similar trend with the final weight. The dietary treatments had no significant influence (p > 0.05) on all haematological parameters determined. A range of 2.90-3.15 ×10 /l was recorded for red blood cell, and 5.710.60×10/l for White blood cell While MCH and MCV random 27.1632.75pg and 88.5589.35fl, respectively. Sorghum based diet supplemented with enzymes showed significant (p< 0.05) on serum biochemical indices. Parameters that were significantly influenced include; Total protein, globulin, urea, creatinine and cholesterol. Rabbits fed sorghum based diet supplemented with phytase (D3) revealed highest (p < 0.05) values for total protein and globulin. Highest (p<0.05) value of 7.05mmol/l,102.25mmol/l and 4.50mmol/l were recorded for urea, creatinine and cholesterol, respectively in the control diet. In conclusion, sorghum based diets supplemented with enzyme improved rabbit performance, had no allergic effect on health status of rabbit and enhanced serum protein bioavailability with efficient nutrient utilization.

Mineral chelators such as organic acids have been reported to compete favourably with phytate by forming soluble complexes with feed minerals. Effect of feed grade acidifiers on total tract mineral retention and intestinal pH of broiler finisher chickens was investigated. A total of 300-broiler finisher chickens were assigned to four treatment groups. Each treatment was replicated thrice with twenty chickens per replicate in a completely randomized design. The control treatment (T1 ) was fed the control diet adequate in available phosphorus at 0.5% while other treatments (T2 -T4 ) were fed sub-optimal available phosphorus diets at 0.4%. Three blends of acidifiers; Fysal®, Orgacid® and Acidomix® were supplemented in the diets of chickens in treatments 2, 3 and 4 at 0.1% (1kg per ton/feed). Chickens fed diet supplemented  with Fysal® showed the best (P<0.05) results in total tract mineral retention 56.5+/-5.75 compared to the control and other treatments. The poor mineral retention i.e. 35 and 46% for calcium and phosphorus respectively by chickens fed the control diet was attributed to the insoluble phytate-mineral complex that limits mineral bioavailability. Intestinal segments of chickens fed acidified diets showed significant reduction (P<0.05) in pH in the range of 5.26-7.16 across duodenum to ileum compared to the control group 6.83-8.76. It is concluded that feed acidification at 0.1% improves mineral utilization in broiler chickens as it competes favourably with phytate in the lumen of the gut leading to better nutrient utilization.
